Game play mods require everyone in the game room to have the mod to keep the game from going of out sync. If anyone joins the room and they don't have the mod installed, Voobly will auto-install it for them. Game play mods are selected in the game room settings dialog. Only one game play mod can used at a time but can be used along with visual mods.
